🧩 JSON Diff

Compare two standard JSON values locally in your browser, ignoring object key order while keeping array order significant.

This version compares standard JSON semantic differences locally in your browser.

  • Different object key order is not treated as a difference.
  • Array order changes are treated as differences.
  • Duplicate-key conflicts are not preserved completely, and numbers beyond JavaScript safe integers may be affected by native parsing precision.
  • It is not a patch, merge, validator, or fixer tool.
